---------------------------------------
HADOOP-14507 might help here
> Oozie Coordinator does not allow us to override hadoop credential provider
> factory at run time
> ----------------------------------------------------------------------------------------------
>
> Key: OOZIE-3180
> URL: https://issues.apache.org/jira/browse/OOZIE-3180
> Project: Oozie
> Issue Type: Improvement
> Components: coordinator
> Affects Versions: 4.2.0, 4.3.0
> Reporter: Mahadevan Krishnan
> Priority: Major
>
> It looks like we cannot override
> _hadoop_.security._credential_._provider_._path_ defined in oozie-site.xml at
> run time per application basis without making changes to oozie-site.xml and
> restarting oozie service?
>
> I am interested in defining my coordinator like this where I need to
> monitor for availability of file in the S3 bucket which is controlled by
> access key and secret access key. This access key and secret access key is
> maintained in application specific JCEK file and hence I cannot define
> _hadoop_.security._credential_._provider_._path_ in core-site.xml or
> oozie-site.xml and I will need to pass this property dynamically for each
> coordinator. I believe this flexibility is not there. It will be good to add
> this feature
